Fimbristylis is a genus of sedges.

A plant in this genus may be known commonly as a fimbry or fimbristyle.

Several continents have native species but many species have been introduced to regions where they are not native.

These are typical sedges in appearance, with stiff, ridged stems and cone-shaped terminal panicles of spikelets.

They are found in wet environments, and are most diverse in tropical and subtropical regions.
